LLVM
LLVM and Python
Past, Present, Future
Python with LLVM has at least one decade of history. This session will be going to cover-up how python implementations tried to use LLVM such as CPython's Unladen Swallow branch (PEP 3146) or attempts from PyPy and why they failed. After that it will show what are the current python projects that use LLVM for speed, such as numba and python libraries for working with LLVM IR. In the end, it will mention about new ideas that would unite the powers of both LLVM and Python.
This talk is about LLVM's influence over Python's ecosystem. It is targeted an audience of language developers who want to integrate LLVM and developers who are curious about why dont dynamic languages can unite their power with LLVM to speed-up. It will start with python's implementations and the approaches they take. The Unladen Swallow branch which basically tries to integrate LLVM to CPython (under google sponsored) is a good example of these approaches. There are attempts from the PyPy side but they are also failed because of the dynamic nature of Python. After this fails, we'll swap back to our current time and show projects that are benefiting from LLVM to speed up python especially on the scientific side such as numba (which offers JITting via LLVM). Besides these projects, there are also a few projects that offer an interface to LLVM. Such as llvmpy and llvmlite. I've been using llvmlite about 1 year in my side projects and toy languages so these projects has the potential to inspire developers to work with LLVM and build languages a-top on it. In the end, it will show what is the future of these two big projects (LLVM & Python) and how we can participate.

The aim of this presentation is to showcase the technologies available in LLVM that aid debugging. We will focus on LLDB, the debugger, and sanitisers (e.g. AddressSanitizer and LeakSanitizer). No prior knowledge is required, but if you're familiar with GDB or Valgrind then this talk will introduce you to alternatives available within LLVM. LLDB is a very powerful and extensible command line debugger available on Linux, Mac OS, FreeBSD, Windows and Android. It is used internally in XCode and ...

Dhrystone and Coremark have been the defacto standard microcontroller benchmark suites for the last thirty years, but these benchmarks no longer reflect the needs of modern embedded systems. Embench™ was explicitly designed to meet the requirements of modern connected embedded systems. The benchmarks are free, relevant, portable, and well implemented. In this talk we will present the results of benchmarking Clang/LLVM for various IoT class architectures using Embench. We shall look at - how ...

GCC is the default toolchain to build C/C packages in Fedora. Meanwhile OpenMandrivia already builds most of its package with the LLVM toolchain, the Debian archive is regularly rebuilt with with a recent verion of clang... So could we try that for Fedora? This talk describes an on-going effort to achieve that goal while keeping the same compiler feature set as GCC.

At the GNU Tools Cauldron we held a panel discussion on how GCC and LLVM can work together. The video of that discussion can be seen at https://www.youtube.com/watch?v=PnbJOSZXynA. We proposed a similar discussion to be held at the LLVM Developers Meeting, but the reviewers suggested that such a discussion would be better held as part of the FOSDEM LLVM Devroom, since that was more likely to attract GNU developers as well. We wish to explore how Clang/LLVM and the GCC can work together ...

The security of computer systems fundamentally depends on the quality of its underlying software. Despite a long series of research in academia and industry, security vulnerabilities regularly manifest in program code. Consequently, they remain one of the primary causes of security breaches today. The discovery of software vulnerabilities is a classic yet challenging problem of the security domain. In the last decade, there appeared several production-graded solutions with a favorable outcome. ...

This talk introduces Flang (F18), the new Fortran frontend of LLVM being written in modern C . The talk will provide a brief introduction to Flang, motivation for writing this new compiler, design principles, architecture, status, and an invitation to contribute.
